DESCRIPTION

FUNCTIONS

None are exported by default, but they are exportable.

bool(%args) -> [status, msg, result, meta]

Arguments ('*' denotes required arguments):

false_char => str

Instead of style, you can also specify character for true value.

in => any

Input stream (e.g. array or filehandle).

notion => str (default: "perl")

What notion to use to determine true/false.

perl uses Perl notion.

n1 (for lack of better name) is just like Perl notion, but empty array and empty hash is considered false.

TODO: add Ruby, Python, PHP, JavaScript, etc notion.

out => any

Output stream (e.g. array or filehandle).

style => str (default: "one_zero")

Y_N: N Y

dot_cross (uses Unicode): ✘ ●

heavycheckcross (uses Unicode): ✘ ✔

one_zero: 0 1

t_f: f t

Return value:

Returns an enveloped result (an array). First element (status) is an integer containing HTTP status code (200 means OK, 4xx caller error, 5xx function error). Second element (msg) is a string containing error message, or 'OK' if status is 200. Third element (result) is optional, the actual result. Fourth element (meta) is called result metadata and is optional, a hash that contains extra information.
